Abstract
The present invention provides a kind of multistage shape memory polystyrene material that stimulation is replied and preparation method thereof, it is partially embedded different sensing heat up particles at different shape memory polystyrene material paragraphs, when applying to stimulate accordingly to whole material, only corresponding paragraph could sense heating and reply, and other paragraph will not be replied, thus achieve the controllability that material is replied.With the multistage shape memory polystyrene material prepared by preparation method involved in the present invention, there is controlled multistage to reply, by changing stimulating method such that it is able to realize replying the controllability at position, and preparation process is simple, workable, contribute to the application at numerous areas such as China's Aero-Space, auto parts and components of the shape memory polystyrene material.
Description
Technical field
The present invention relates to a kind of multistage shape memory polystyrene material stimulating reply and preparation method thereof.
Background technology
The novel intelligent that shape-memory polymer (Shape Memory Polymer, SMP) rises just at present
Material, it has light weight, deformation quantity is big, be prone to drive, low cost and performance adjustable range big etc. are
The performance that row are excellent, is to prepare the material that the extraordinary devices such as space extendable device are highly desirable.But due to it
The uncontrollability at recovery of shape position so that the application of such material exists the biggest restriction.So preparation has
Multiple stimulation, the shape memory polymer material of the controlled recoverability of multistage are significantly.Shape memory
Polymer is the class in novel intelligent material, by different environmental stimuli condition such as ultraviolet light irradiations, temperature
Field change, electromagnetic field change etc., it is possible to bring it about the respective change being pre-designed, from temporary shapes to original
The change of shape.Multistage stimulates reply shape memory polystyrene to be also the one in shape-memory polymer.And
And the controlled shape memory recovery effect of multistage makes it have quite varied application potential.Shape memory polyphenyl
The application that ethylene is currently mainly mentioned is at aerospace field, compared to traditional polystyrene shape note
It has the controlled ability of outstanding reply to recall polymer.This makes this material can apply in aerospace craft
The positions such as controlled deployed configuration.
Summary of the invention
It is an object of the invention to provide a kind of multistage and stimulate the shape memory polystyrene material and preparation thereof replied
Method.
The technology used in the present invention is as follows:
A kind of multistage stimulates the preparation method of the shape memory polystyrene material replied, and comprises the steps:
Step one: be the Fe of 20nm by thickness state shape memory styrene and mean diameter3O4Nano-particle stirs
Mix mixing, ultrasonic disperse again after mixing, make Fe3O4Nano-particle is evenly dispersed in matrix, described
Fe3O4Nano-particle is the 5% of shape memory styrene quality；
Step 2: by the thickness state shape memory styrene obtained by step one and Fe3O4Nano-particle is blended molten
Liquid is placed in mould, is then placed in drying baker carrying out precuring, and temperature conditions is 75 DEG C, and hardening time is
0.5 hour；
Step 3: afterwards another part of liquid form memory styrene is poured on the precuring thing obtained by step 2
Fang Jixu solidifies 0.5 hour；
Step 4: last just thickness state shape memory styrene mixes with the stirring of multiple CNTs, then will
Finely dispersed composite solution is poured into above the precuring thing obtained by step 3, then enter 24 hours the most solid
Changing, the multistage i.e. obtaining the present invention after being fully cured stimulates reply shape memory polystyrene material, described carbon
Nanotube is the 0.5% of polystyrene quality, carbon nanotube sizes: diameter 20-30 nanometer, length 20-30
Micron.
The present invention also has a following technical characteristic:
A kind of multistage stimulates the shape memory polystyrene material replied, at different shape memory polystyrene materials
The sensing heat up particles that material paragraph embedding is different, when applying to stimulate accordingly to whole material, the most accordingly
Paragraph could sense heating and reply, and other paragraph will not be replied, it is achieved that the controllability that material is replied.
Beneficial effects of the present invention: the multistage that the present invention is prepared with shape memory polystyrene for matrix stimulates reply
Shape memory polystyrene material there is multiple stimulating method, and the most corresponding under different incentive conditions
The feature that could reply of paragraph position.And can be multiple by changing by the preparation method designed by the present invention
Close the type of granule such that it is able to realize replying the controllability at position, and preparation process is simple, workable,
Contribute to the application at numerous areas such as China's Aero-Space, auto parts and components of the shape memory polystyrene material.
Accompanying drawing explanation
Fig. 1 is that this multistage stimulates reply shape memory polystyrene material schematic diagram.
